Description
Labcenter Electronics Proteus PDSPRJ File Parsing Type Confusion Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Labcenter Electronics Proteus. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDSPRJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25717.
Analysis
Type confusion in Labcenter Electronics Proteus PDSPRJ file parser enables remote code execution when users open malicious project files. Attackers exploit insufficient validation during file parsing to trigger memory corruption, achieving arbitrary code execution with victim user privileges. …
